Scary dude, you may not have got off the underground in one piece! By the way, I watched a cookery programme about restaurants and bars in New York, your work is amazing - it was like watching a moving history of your work!

Roderik, I always try to draw without being noticed which is way most of my subjects are reading or sleeping, only a couple of times in 4 has anyone objected and that was just a simple case of putting the sketchbook away.
